of the synchronous inductance of tooth-coil permanentmagnet
synchronous machines are reevaluated in this paper.
The inductance estimation is different in the tooth-coil machine
compared with the one in the traditional rotating field winding
machine. The accuracy of the analytical torque calculation highly
depends on the estimated synchronous inductance. Despite powerful
finite element method (FEM) tools, an accurate and fast
analytical method is required at an early design stage to find an
initialmachine design structure with the desired performance. The
results of the analytical inductance calculation are verified and
assessed in terms of accuracy with the FEM simulation results and
with the prototype measurement results.
